"Everybody tells me, 'Please run for president. Please run for president,'" Trump told attendees at last week's Oakland County Republican Party Lincoln Day Dinner in Novi, Mich. "I would be much happier if a great and competent person came along. I'd be happy if President Obama did a great job. I'm a Republican, but before anything, I love this country. I would love to see somebody come in who is going to be great."

Now, sources say he has invested more than $1 million to gauge his popularity in each state.

"The electoral research was commissioned. We did not spend $1 million on this research for it just to sit on my bookshelf," Michael Cohen, executive vice president and special counsel to Trump, told the New York Post. "At this point Mr. Trump has not made any decision on a political run, but what I would say is that he is exactly what this country needs. The turnout at these political speeches indicates his following remains very strong and is growing."

In his Michigan speech, Trump predicted Hillary Clinton would be the Democratic front-runner, and that if Republicans "don't pick the right person, it will be a landslide," according to the Post.
